At Banco do Brasil, I led backend development for internal APIs and critical features supporting mobile and internet banking. I designed and implemented a facial recognition system for mobile transactions and a reusable feature flag solution adopted across multiple microservices.
I improved unit test coverage by 85% using JUnit and enhanced CI/CD pipelines with automated validations.
At Itaú, I modernized 70% of a legacy warranty control platform with microservices and event-driven messaging on AWS. I also designed a secured loan contracting flow and led a squad of five developers as Tech Lead for one year.
At Infosolo, I designed and developed web systems, mobile applications, and RESTful APIs with Java and Spring Boot. I also worked with AWS and microservices on cloud-native solutions.
